Abstract
A security USB connector implements an intrusion prevention function preventing the propagation of malicious codes to a host terminal from a USB device while minimizing host terminal resource consumption, and an intrusion prevention system using the same are disclosed. A security USB connector is positioned between the host terminal supporting a USB host and a USB device, and a security inspection is performed on data transferred from the USB device to the host terminal through the security USB connector. Also, a host terminal without an intrusion prevention function can prevent an intrusion by using the portable security USB connector.
Claims11
A security USB connector comprising:
- a security policy database (DB) storing a security policy;
- a USB transceiver supporting data transmission and reception between a host terminal and a USB device, and stopping data transmission and reception between the host terminal and the USB device if USB data transmitted from the USB device contains a malicious code;
- a contents filter inspecting whether or not the USB data contains a malicious code based on the security policy stored in the security policy DB when the data provided from the USB transceiver is the USB data;
- and
- two or more USB interfaces physically connecting with the host terminal and the USB device, respectively.
An intrusion prevention system comprising:
- a host terminal having a USB host function;
- a USB device storing and providing USB data;
- and
- a security USB connector physically coupling the host terminal to the USB device, and transferring the USB data from the USB device to the host terminal only when the USB data does not have a malicious code.
